Hello list. I once had a samba server acting as a PDC, a mapping between my NT 'Domain admins' and Unix 'admins' groups, and everything worked perfectly. Now I got a new shiny samba server acting as a print server only, member of an AD domain, and I can't have the members of 'Domain admins' group manage printing drivers on the server, whereas the Administrator

Salutations: I have been trying to translate a S-PLUS/ArcInfo (GIS software) application that I wrote on a SGI (IRIX) platform to public domain R and GrassGIS on a Linux platform. I am almost on the verge of abandoning it as I find R to be rather unstable, slow and frustrating. I enclose a section of my code for R experts to examine hoping that they'll point out that all the above three are

Hello list. I recently moved to an AD environment. I'm still keeping a samba servers to make my cups-managed printers available to windows users, rather than duplicating configuration with a Windows print service. But I'm facing two problems, probably due to the way we manage AD. First, all my host belong to a Unix-managed DNS domain (msr-inria.inria.fr), not to the windows-managed

Hola, Acabo de calcular tf-idf y me surge una duda. ¿Habría un valor de idf o tf-idf que se considerara como umbral para establecer que una palabra es muy común o no? Los valores de idf en mis datos van entre 0 y 3.78 y los de tf-idf ente 0 y 0.07.

Hello guys.I have sent a pull request for the code and tests of the Tf-Idf weighting scheme. Please do let me know if any changes are required.Meanwhile,Ill begin working on implementing normalizations which require additional statistics and on the DFR schemes. https://github.com/xapian/xapian/pull/6 On Tue, Feb 26, 2013 at 5:30 PM, <xapian-devel-request at lists.xapian.org>wrote: >

df is a very large data frame with arrival estimates for many flights (DF$flightfact) at random times (df$PredTime). The error of the estimate is df$dt. My problem is that I want to know the prediction error at each minute before landing. This code works, but is very slow, and dominates everything. I tried using split(), but that rapidly ate up my 12 GB of memory. So, is there a better R way of

Hi, I have some questions about the way that documents are scored by the Boolean and MultiTerm Queries, and about possible options for custom scoring articles. I am working on a project experimenting with different methods of automatically generating queries and the scoring mechanisms behind Lucene and Ferret have been perplexing us. >From looking at the Lucene explanation at (

Hi, I''m confused about managing field boosting ... I have set the :boost for the :name field in my docs to 10, via :boost => 10 Then I performed a search for ''keith'' over all fields via with *:(keith*), expecting a doc with Keith in the :name field to come out on top. But another doc with Keith mentioned in other fields (:comments, :address) scored higher. I

Hello guys.I just read up about tf-idf schemes and want to implement it in Xapian (with some frequently used normalizations) as it will also give me a good hang of implementing a weighting scheme before I start working on implementing DFR schemes. I read the following as references and I think Ive understood it well and can write the hack :- 1.)

I create a data.frame using : alloc <- data.frame(matrix(nrow=length(unique(mid2agi$gene)), ncol=8)) colnames(alloc) <- c('agi', 'hit_len', 'q_len', 'identity', 'ratio', 'e', 'ok' ,'gene') alloc$gene <- unique(mid2agi$gene) this results in: > head(alloc) agi hit_len q_len identity ratio e ok gene

Hey guys, Simple question here. I have a single index of recipes, from which I''m looking at the following fields: Name, Ingredient Text, Tags, and Description. The key is, I want to show all the results that come from Name, before I show any of the results from Ingredient Text, Tags, or Description. I tried doing this: acts_as_ferret :fields => { :name =>

I saw Tanya's note about this year's LLVM developers' meeting. It would be interesting if the time could coincide with IDF 2009 (Sep. 22-24). I'm sure some LLVM folks would be interested in attending IDF as well. Perhaps hold the LLVM conference the day before or after IDF? -Dave

Dear R users,I'm a new user of R. I'm trying to do a LM test an there is this type of error: Error in t(mX) %*% mX : requires numeric/complex matrix/vector arguments. To be clear I write down the code in which mY ( 126,1 ) mX (126,1) mZ(126,1) are matrix. LMTEST <- function(mY, mX, mZ)#mY, mX, mZ must be matrices!#returns the LM test statistic and the degree of freedom{iT =

I tried to use dovcots lmtp instead of dovecot-lda. postfix has in master.cf ... dovecot-lda -f ... -d ${user} to separate the user part from user at hostname.domain. So lookup of "user" succeeds in userdb (LDAP) done by dovecot-lda. I have always local addresses like to=<user at hostname.domain> postfix/lmtp[6579]: [ID 197553 mail.info] B3CDA66A16: to=<h0094slk at

Hello R people I now know how to run my discriminant analysis with the lda function in MASS: lda.alain=lda(Groupes ~ Ht.D0 + Lc.Dc + Ram + IDF, gr, CV = FALSE) and it works fine. But I am missing a test and cannot find any help on how to get it, if it exist. The "S" equivalent: discrim(structure(.Data = Groupes ~ Ht.D0 + Lc.Dc + Ram + IDF, class = "formula"), data = gr,

Don''t let the bureaucratic aspects of this RFP bother you: we''re eager to find and work with a good trainer to get our developers up to speed on RoR, and there''s a possibility of a paid Rails-evangelist gig as well. If that sounds like something you would be interested in and qualified for, I hope you will get in touch with us and submit a proposal. --Chris
